Create a minimum phase filter from an elliptic digital filter

The impulse response hmp is computed by convolving the impulse response of the elliptic filter with itself. We know that the elliptic filter is marginally minimum-...

Audio is sampled at 48 kHz, or 48000 samples per second. Does that mean 48000 bits (or 6000 bytes) of storage?

For raw, uncompressed audio, the number of bits per second is the product of three values: $$ numBitsPerSecond = f_{sampleRate}*numBitsPerSample*numStreams $$ where $f_{sampleRate}=48000$ in your ...

Create a minimum phase filter from an elliptic digital filter

A filter is minimum phase when all it's poles and zeros are inside the unit circle. The easiest way to check is to inspect the zeros and poles of the filter and look at the magnitudes ...

Will open, edit, store from/to lossy audio format significantly degrade quality?

This really depends a lot on what exactly the processing is. Cutting out unwanted parts of the signal will have very little impact on the parts that you keep. Ogg Vorbis is block based and the largest ...

How to find the "minimum spectrogram" across multiple recordings to extract a common audio signal?

First, is there any reason this wouldn't work, That's a reasonable approach but the devil is in the details. You will have to figure out the right framing approach (frame size, window, overlap, etc) ...

Audio is sampled at 48 kHz, or 48000 samples per second. No. Audio is often sampled at 48000 samples per second. It can be sampled at a number of different rates. The old-time digital telephony ...
